Description of X-W10D4:

OVERVIEW
The New X-Series subwoofers were developed from a sound philosophy we call Alpine ID – a focus on highly accurate components built for superior imaging. A triple stacked magnet surrounds an extended voice coil which allows a very long excursion resulting in huge air movement.

A specialized CRC pole with integrated cooling fins and an aluminum shorting cap reduce the lag of coil’s alternating movement while also providing cooling within the motor. The cone structure is suspended by two spiders and our patented H.A.M.R. surround. The stability of the dual-spider along with the even unfolding of the multi-roll surround create incredibly linear cone travel, free of any unneeded movement that cause distortion.

The powerful and efficient motor coupled with its highly-controlled suspension give the X-Series subwoofer the ability to create loud and accurate bass in a very small, sealed box. Only requiring 1 cubic foot of air space (.55 for the 10”), the 12” X-Series subwoofer can reproduce frequencies down to 40 Hz before rolling off, leaving you with bass that digs deep and plenty of trunk space.

The new X-Series subwoofers are the X-W12D4 12-inch Dual 4 Ohm and the X-W10D4 10-inch Dual 4 Ohm.

CRITICAL EVALUATION OF IN-CAR SOUND
Alpine’s top engineers from all over the world gathered in Alpine headquarters to deeply research and evaluate sound systems from both the aftermarket and high-end OE manufacturers. Many systems today have incredible dynamic range and reach sufficient volume levels, but lacked the reality of instruments and spatial imaging. As a result, Alpine ID was born, a sound philosophy that continues to inspire us to create a new level of sonic performance.

ALPINE: IMAGE DEFINED
Or Alpine ID for short, is the new Alpine global sound culture with an evolutionary approach for solving what’s missing in most car audio systems these days: great spatial imaging and depth of sound stage. It centers on developing matched sound systems with core components that work together to achieve greater realism in the sound stage while maintaining great dynamic range and accuracy.

BUILT TO MOVE TONS OF AIR
The 24mm Xmax is best in class and allows close to 2 inches of full cone motion. In order to create a powerful yet accurate subwoofer, we had to implement several technologies that keep the cone under control. Dual spiders ensure a rigid moving assembly while the HAMR surround provides long linear travel. A shorting ring keeps the THD down while a custom heat sink integrated CRC pole and shorting cap keeps high magnetic force. These design aspects come together to produce incredibly precise, powerful bass.

EASY GRILLE AND TRIM RING INCLUDED
Taking design cues from tweeter development, we’re incorporating a twist-lock trim ring which allows easy attachment of the included metal mesh grill. With a simple twist, the trim ring locks into place, concealing the mounting screws and locking the optional grille into place. The trim can be installed with or without the grille.

THE PERFECT PAIR PERFECT POWER MATCHING
The X-Series amplifier, X-A90M, is the perfect amplifier for the job. Along with the 900w power matched specifications of both components, each were built under the same sound philosophy, Alpine ID. With a focus on musicality and sound imaging, the X-W10D4 is complimented by the amplifiers clean, low distortion output and >1500 damping factor. Add the X-Series speaker to the system and prepare to experience a new level of in-car imaging.

Includes: 

• 36 Square Foot Roll of Rockmat Sound Dampening Material
• Roller for a perfect installation

The Rockville Rockmat RM36 sound dampening material is a must have for any professional car audio install. This package includes 9 sheets that are each 4 square feet. This gives you a total of 36 square feet. We also include everything needed for a quick and easy installation! Our Rockmat will increase how loud your car stereo plays! It also improves bass quality and eliminates those bad rattling and distortion sounds.

Installing Rockmat improves bass quality of the speaker and eliminates those bad rattling and distortion sounds.

Our Rockmat is built to the highest standards in this industry using 100% butyl rubber with a layer of heat resistant aluminum.  Butyl rubber is the same material high end speakers surround material is made out of. We use the highest quality pressure-sensitive self-adhesive to make your installation quick and easy. Our model has increased flexibility for an easier and more permanent installation! Our sound dampening product uses 72mil of pure grade aluminum! Most products on the market use 50mil. Our product will absorb sound better than the competition. If a product does not specify how much material is being used, you should be very cautious about it! Every manufacturer should know what they put into their products! Also, other products on the market such as GTMAT for example use a mixture of asphalt in their products. They basically are manufacturing roofing material and calling it sound deadener. Their product will work OK, but not nearly as good as our Rockmat. Our Rockmat is made of butyl rubber and aluminum which is the same as many of the more expensive brands out there that sell for twice our price.. We do not cheat our customers. We only make top quality gear over here at Rockville!

Our Rockmat has an adhesive temperature range of -100F to 300F (-60C to 150C). Our adhesive is top of the line! It will stick for years and years! Each layer of our material reduces unwanted noise 5-8 dB! This is among the best ratings in the industry. Our product works as well or better than other high end brands! We did our testing and research.

We make all our models in 2 color options. You get the choice of black and silver. We decided to also keep the look very clean! We see all these other brands tattooing their logos all over the material. I always thought it looked stupid. So I made sure to keep our Rockmat with a clean look to it.

Installation Instructions:
Rockmat is a self-adhesive. Stick the Rockmat in your desired area. Rockmat is pressure sensitive so after you apply the material into your desired area; apply pressure to it. That is it! Installation takes only minutes! Please note our Rockmat is also easy to cut into the desired shape you need!

To prove how good our sound dampening material is we will offer a 90 day money back guarantee! If you are not happy with the performance; simply pack it up and we will send you a label and give you a complete refund when it comes back to us!
